摘要： PROBLEM TO BE SOLVED: To provide a copper-based bearing material with a titanium or titanium alloy back plate by a continuous sintering method and a continuous roll pressure-welding method suitable for mass production and manufacturable at a low cost.
SOLUTION: The back plate 3 is formed of Ti or Ti alloy, and an intermediate layer 4 formed of Fe or Fe-Cr alloy is provided between a copper-based bearing layer 2 and the back plate 3. The direct contact of Ti or Ti alloy with metal liable to form an intermetallic compound or with gas is thereby prevented to suppress the formation of the intermetallic compound or a compound with gas. Furthermore, since Fe and Cr used for the intermediate layer 4 are not liable to form an intermetallic compound with Ti at a heat treatment temperature after sintering and pressure welding of a Cu alloy, the copper-based bearing material 1 using Ti or Ti alloy for the back plate 3 can be manufactured without lowering the strength of the copper-based bearing material 1 by the continuous sintering method or the continuous roll pressure-welding method manufacturable at a low cost while allowing sintering and heat treatment.

摘要翻译：要解决的问题：通过连续烧结法和连续辊压焊接方法提供具有钛或钛合金背板的铜基轴承材料，适用于大规模生产并以低成本制造。解决方案：背板3由Ti或Ti合金形成，并且在铜基轴承层2和背板3之间设置由Fe或Fe-Cr合金形成的中间层4。直接接触因此，可以防止易于形成金属间化合物或气体的金属的Ti或Ti合金抑制金属间化合物或气体化合物的形成。此外，由于用于中间层4的Fe和Cr在Cu合金的烧结和压接之后在热处理温度下不易与Ti形成金属间化合物，所以使用Ti或Ti合金的铜基轴承材料1 可以通过连续烧结法或连续辊压焊方法在不降低铜基轴承材料1的强度的情况下以低成本制造背板3，同时允许烧结和热处理。版权所有（C）2004，JPO
